The first appearance was as a serialized novel, published in The Lady's Realm, November 1906 through October 1907. J.R. Skelton created 54 illustrations.
McKay, Scott, and Whatmore claim that Hutchinson and Company published the first edition in book-form in London on September 9, 1907. Apparently 15,000 copies were printed, with only 15 of Skelton's illustrations. Ads at the end of the book are dated August 1907.
Longmans, Green, and Company published the first edition in book-form in New York on October 11, 1907 with the shortened title, MARGARET, and included 16 of Skelton's illustrations. Ads at the end of the book are not dated. McKay and Scott both agree on the publication date in New York.
The Musson Book Company published the first edition in Canada. There is no date within the book, and no ads at the end.
See the VisualHaggard.org page dedicated to the illustrations found in various editions.
